Various shots of an old fashioned dredger at work on the Norfolk Broads. M, S from a moving boat of the new Jetlift dredger; it looks very snazzy in bright yellow.

M, S of pipes of the dredger being raised up as one of the men signals for the lifting to stop.

C, U of the other man in the control box, smoking a pipe. At the signal he lowers the pipes again. High angle M, S as the pipes are submerged in the water. M, S of pipes on marshy, swampy land with water spurting out of them.
